Title: Apparatus for displaying cable trouble point
Inventor: ENOKIDO KIYOMASA
IPC: G01R31/08
Filed: 1985-12-16
Abstract: PURPOSE:To make it possible to detect a trouble point regardless of the magnitude of the damage of a trouble point, by detecting the time difference of vibration energy generated at the time of trouble. CONSTITUTION:When it is assumed that trouble was generated at a point (x), impulsive vibration energy propagates through a connection point 2 and a cable 1, for example, at a speed of 1,000-5,000m/s. Therefore, if response elements 31 are arranged on a surface at an 1m-interval, time delay comes to 1X10<-3>-2X10<-4>s/m. In the display device nearest to the point (x), each element 31 receives vibration energy to convert the same in to a voltage signal and LED 34 is allowed to go on the basis of said voltage signal through a SCRDC switch 33 and the voltage signal is amplified by an amplifier 32 to be transmitted to the other display device 3 through a signal electric wire 4 so as to be delayed, for example, a time of 3.3X10<-9>s/m. Therefore, in the display device 3, the switch 33 is cut off by the transmitted voltage signal and the element 31 receives vibration energy delayed about 10<-5>s in arriving and, if the voltage signal is generated, the switch 33 is already turned OFF at this time and, therefore, LED34 does not light up and the trouble point can be detected and displayed.

IPC: G01D21/00
Filed: 1987-11-09
Abstract: PURPOSE:To make the title method economical and to always correctly evaluate the operating state of a plant deciding the existence of abnormality in a process variable detected by collective decision based on mutual cause and effect relation between respective process variable featured by the constitution of the plant. CONSTITUTION:At the time of inputting abnormal signals from respective diagnosis parts 101-104, a process state integrated diagnosis part 106 decides the existence of abnormality in a process variable P2 e.g. by decision logic based on the mutual relation between respective signals, and when a detector is abnormal, outputs a signal 201. Simultaneously, the integrated diagnosis part 106 outputs a normal forecasting value request signal 202, finds out a normal forecasting value from its relational formula, inputs the obtained value to a process signal processing part as a forecasting value P2' 203, and substitutes the P2' for P2 to evaluate the process variable of the plant. Consequently, the operating state of the plant can be always correctly evaluated for all plant operation by said simple method without forming a complex plant simulation model.

Title: Switching power supply
Inventor: SUZUKI YASUSHI
IPC: H03K17/687
Filed: 1988-11-09
Abstract: PURPOSE:To stabilize output voltage by providing a bypass circuit composed of a thyristor turned ON-OFF in response to the output voltage of a DC power, a comparator comparing a capacitor for charging and the potential of the DC power, a resistor for charging the potential of the capacitor for charging up to the output voltage of the DC power and a diode. CONSTITUTION:A comparator 20 compares the voltage of a capacitor 14 for charging and the output voltage of a DC power 1 and transmits a signal when both voltage equalizes, and a thyristor driver circuit 22 receives the signal from the comparator 20 and turns a thyristor 21 ON. Many time is required for charging the capacitor 14 for charging to high voltage only by charging currents in stationary operation, but the time up to the completion of charging can be shortened only by the instantaneous charging of the capacitor 14 when the capacitor 14 is charged instantaneously up to the output voltage of the DC power 1 by a bypass circuit consisting of a resistor 18 and a fourth diode 19. Accordingly, the output voltage of the power supply 1 can be kept stable.

Title: Electron-beam lithography apparatus and pattern formation
Inventor: MAEHARA HIROSHI
IPC: H05K3/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To enable control of an etching pattern having a point-symmetrical shape into an arbitrary shape. SOLUTION: Drawing of a plurality of patterns having different radii is carried out with respect to a resist coated on a substrate S, while a substrate S is rotated at an arbitrary angular velocity, to find one of the pattern radii providing an optimum quantity of light exposure after development. Next, the angular velocities of the patterns of other radius are calculated on the basis of the found optimum pattern radius. The incident direction of a light beam relative to an arbitrary position on a diffraction optical element thus formed is calculated by a beam-tracing method. Continuously, the substrate S for the diffraction optical element is prepared, and a diffraction optical element pattern is drawn by electron beam exposure after resist film formation.  At this time, the substrate S is etched with an ion beam, while controlling the tilt angle of the substrate so that the incident direction of the beam at the previously-found position on the element becomes parallel to a pattern sidewall for obtaining a pattern for the optical element having the pattern sidewall parallel with respect to the incident beam to the element.

Title: Ultrasonic inspection apparatus
Inventor: KAJIWARA JUNICHI
IPC: G01B17/00
Filed: 1994-11-17
Abstract: PURPOSE: To always detect the defect in a test specimen with the same accuracy by altering the gains before and after the surface echo from the test specimen is detected. CONSTITUTION: An ultrasonic inspection apparatus can be DAC controlled, radiates an ultrasonic signal to a test specimen with a pulse trigger point as a starting point, and retrieves the point where the echo reception signal from the test specimen exceeds a predetermined threshold value. The retrieval is continued while a gate generator 8 outputs a gate signal. If the echo reception signal from the specimen test exceeds the predetermined threshold value, i.e., the surface echo is detected, a DAC trigger signal is supplied to a DAC curve generator 9, which outputs a DAC control signal, and supplies it to a preamplifier 3. Thus, the output level of a video amplifier 7 becomes substantially constant without depending upon the measuring time, i.e., the depth of the test specimen.

Title: Memory supervisory and controlling system for main signal by odd/even number alternate check
Inventor: NAGAMOTO MAMORU
IPC: H04L12/931
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To improve the supervisory ability of a main signal memory by counting addresses at the time of write and read, measuring the data storage amount of a main signal memory part and switching the odd/even number of a party bit, when a prescribed value is reached. SOLUTION: When a write address is generated from a write address counter 4, a state management part 6 adds one to the data storage amount. A change point detection part 8 monitors the data storage amount of the state management part 6, and when the prescribed value is reached, sends odd/even number switching signals to a parity generation part 1 and switches the off number/even number of a parity. At the same tome, the prescribed value is loaded to a down counter 7. In the other hand, when a read address is generated from a read address counter 5, the data storage amount of the state management part 6 and the down counter 7 and the counter value of the down counter 7 are decreased by one.  Here, when the counter value of the down counter 7 turns from '1' to '0', the change point detection part 8 sends the odd/even number switching signals to the parity generation part 1 and switches the odd number/even number of the parity.
